What's a GeneRIF?

Low TEX40 expression is associated with asthenozoospermia.
Title: Proteomic analyses reveal lower expression of TEX40 and ATP6V0A2 proteins related to calcium ion entry and acrosomal acidification in asthenozoospermic males.
The frequency of the ESRRA/C11orf20 gene fusion in serous ovarian carcinomas of stages III and IV must be very low.
Title: Low frequency of ESRRA-C11orf20 fusion gene in ovarian carcinomas.
ESRRA-C11orf20, a gene fusion between ESRRA and C11orf20 (TEX40) is recurrent serous ovarian carcinoma.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
